650w 970 SLI
i made a thread before about 970 sli psu, and i was told that OCZ ZT650w wont be enough for it but then i saw this video in youtube and was shown that they had 464w usage while playing crysis 3 on 4k with a much superior processor and it was overclocked too. (i7-4770K on 4.5Ghz which i suppose uses like 50w more than my i5-4570)
so i not sure now. guru3d says recomended 800w , some thread here said that need 665w. while online calculators were showing ~500w recommended. (biggest i seen was 497 minimum and 547 recomended psu wattage).
so i not sure if my zt650w is enough for 970 sli if i wont be doing any overclocks

Your PSU will be able to handle it. 54 amps is enough.

Its closer to the limit than many people will be happy with, but thankfully the new maxwell GPUs are very power efficient if you dont go for crazy overclocks.

Id surely recommend 800w or at least 750w min. although the GPUS will not chew up much when running at normal or full use, you still have to consider when you turn on your PC it will use the max wattage to get them up and running, if you do not have proper power to them they could short and become paperweights.
